To @ZZ whom, t mfctg concern:

Beit known that l, ALFRED T. TREGURTHA, of Everett, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Machines for Applying Met-al Coverings toSpool-Heads, of which the following is a full, clear, and exactdescription,

This invention relates to a machine for covering the edges of the headsof spools or bobbins with metal in accordance with Letters Patent of theUnited States, for improvements in spools or bobbins, dated August 5,1890, No. 133,885; and the invention consists of a machine constructedand arranged to cover the edges of heads of spools or bobbins, allsubstantially as hereinafter fully described, reference being had to theaccompanying sheets of dra-win gs, in which is illustrated a machine inaccordance with this invention, in which- Figure 1 is a front view. Fig.2 is a plan view. Fig. 3 is a vertical cross-section on line 3, Fig. 1.Fig. 4. is a vertical cross-section on line e e, Figs. 1 and 5. Fig. 5is a detail plan view. Fig. 6 is a plan view of one of the parts belowline 6 6, Fig. 11. Fig. '7 is an under plan view of one of the partsjust above the part shown in Fig. G. Figs. 8, 9, and 10 are detailsections of a head of a spool, showing the manner of covering its edgewith the metal in the operation of the machine to be hereinafterreferred to. Fig. 11 is a detail section of some of the parts in Fig.aon same section-line, but showing parts in different positions. Fig. 12is adetail view of a portion of Figx, showing parts in differentpositions. Fig. 13 is a detail cross-section of a spoolhead and theparts holding it. ures, except Figs. 1, 2, and I3, are enlarged.

In the drawings, A represents a lathe-bed having feet B and adapted torest on a suitable bench and be secured thereto by screws passingthrough holes a in the feet B.

C is a head or standard rigidly secured to the lathe-bed A at the left,Figs. 1 and 2, which head has a horizontal shaft D arranged to turn inbearings E in the head and having a pulley F secured to the shaftbetween the bearings for operation by a belt in the usual manner.Secured to the inner end of the All the iig-v shaft by a iange ZJ is acircular plate or disk G, having its outer side hollowed out or con-'cave to leave a narrow bearing-surface cl near the edge. 0n the otherend of the lathe-bed is a standard H, adapted to fit upon the lathebedand be moved back and forth thereon in the usual manner of arrangingsuch standards on a lathe-bed, and which standard, when moved along thebed to any point desired, is secured by a screw-nut .l having a handlee. This standard has in a bearing f in its upper end a horizontal shaftor rod K adapted to freely turn and move forward and backwardlongitudinally in the bearing, which shaft or rod centers with the shaftD, as usual in lathes, and it has secured to its inner end a circularplate or disk L having its outer side concave and having abearing-surface cl near the edge like the other plate G. (See Fig. 13.)ln between these two disks or heads G L is placed the spool M to beoperated upon, a center pin g of each shaft projecting beyond itsrespective disk and entering the central socket h, as shown in Fig. 13,in the spool M, which centers it in the machine.

On the outer end of the shaft K are two circular flanges m, betweenwhich is a box or bearing N, on the shaft, to which box, on its upperside, at n, is pivoted a horizontal lever P, having a handle r,extending forward, its other arm t extending back and being pivoted at'u to a link Qin a longitudinal slot QJ, which link at its other end bya longitudinal slot w is pivoted at g/ to a bracket-arm R of thestandard H. A spiral spring T is secured by one end to the lever at cand byits other end to the bracket at ZJ', and it acts to hold saidleverback and to return it thereto afterit has been moved in theopposite direction.

Secured to the standard H by one of the screws d of the bearing is astrip or bar U, having on its edge two ratchet-teeth e', with which areadapted to engage two projecting teeth f of a dat piece V pivoted to thelever P at g and having a iiat spring 7i secured to the lever at m',arranged to bear by its free end against the pivoted piece to hold it toits engagement by its teeth f with the teeth e' of the bar U when thelever is moved into position therefor.

IOO

To secure the spool M by its socket 7L over the center pin of shaft D,between the two heads G L place one end of the spool, its head n bearingagainst the disk G, and release the nut J of the standard H by turningits handle to the right, Fig. 2. Then release the leverpiece V from itsengagement with the bar U, if not already released,which can be done bytaking hold of an upright pin r' of the piece and moving it forwardtherefrom. Then move the standard H along the bed to the left until itsshaft-pin g enters the spool-socket and its disk L bears and pressesagainst the other head t' of the spool. Then press the lever to theleft,which forces the shaft K byits connection with it by the iianges malong its bearing and moves and presses its disk against the spool-headand the spool closelybetween the two disks, moving the standard backsomewhat, and when it has moved back enough for the bar-teeth e' to benearly to the teeth f' of the pawl U of the lever the nut-handle e isturned to the left, which sets the nut and securelyfastens the standardto the bed at such place. Then the handle portion 7' of the lever P ispressed to the left against its spring until its pivot-piece orinterlocking pawl V engages with the bar-teeth e' on the standard H,which by its spring will then hold the spool firmly between the twodisks G L by a constant pressure, so that by turning the shaft D thespool will be turned with it for operation thereon.

To remove the spool from the machine, move the lever P to free the pawlV from the bar U. Then move the pawl V back by its pin 0*', disengagin git from the barU, and then move the lever bacl;,wl1ich moves the shaft Kback, .leaving the spool free to be taken from the machine,when anothercan be placed therein in position, as before, the standard H remainingset for the same-sized spool.

The slots w in the link-piece Q allowsufficient movement of the lever Pagainst its spring, after the standard is set for it to be moved, topress the disk L and head firmly against the spool.

\V is a block adapted to move back and forth along the lathe-bed by itsunder shouldered grooves, and having an upper dovetail tongue or rib u',over which is a plate A', which has a dovetail groove '1J' on its underside to fit over he block-tongue u' and which can slide back and forththereon and transversely to the lathe-bed, being operated by a screwB',which screws into the plate A' at w', the turning of the screw movingthe plate A' back and forth on the block lV and transversely in relationto it and the lathe-bed, all substantially as usual in lathes andneeding no more particular description herein.

C' is a central vertical pin screwing into the plate A' to be rigidlyconnected thereto, and resting on the plate and adapted to turn on thepin C' s a worin-gear D' engaging with a worin E' on a horizontal rod orshaft F' turning in bearings in blocks G' secured to the edge of theplate A', the rod having shoulders to bear against the adjacent ends u"of the blocks to prevent longitudinal movement thereof.

Above the worm gear-wheel D' is a disk or cam-plate H', (shown in planin 6,) eccentrically secured to the pin C', and above this cam-plate H'is a disk or circular plate J adapted to revolve on the pin C'.

The worm-gear D' has an annular chamber K in its upper side, in which isdisposed a fiat coiled spring L' secured by its inner end to a pin a2 ofthe cam-plate H' and by its other end to a downwardly-projecting pin b2of the disk J The under side of the disk J has a circular rim M' forminga chamber D, in which is disposed the cam-plate H', and to the underside of the disk, in an opening Z2 in the rim, is pivoted at c2 a pawlN', its pointed end f2 extending into the disk-chamber, as shown in Fig.7, and arranged to bear against the edge or periphery of the cam-plateH', as shown in dotted lines in Figs. 6, 7, and 12, and its otherright-angular end g2 adapted to project at ce1'- tain times beyond theouter periphery of the rib M', as shown in Fig. 7, to be hereinafterreferred to, it being held to such position by a spring P' secured at h2to the inside of the disk J' in the chamber to bear by its free endagainst the end of the pawl, as shown in Fig. 7, for such purpose.

In depressions in the upper side of the rim of the gear D', secured byscrews n2 at regular intervals apart, are plates Q', each of which hasan upwardly-projecting lug R', which when the circular plate J is inplace over the cam-plate H' and gear D' projects into the space beyondthe rim M' of the plate J', so that at certain times when the plate J'is turned on the pin C' into certain positions in relation to thecam-plate H' the end g2 of the pawl N' will be swung outward for it tobe in the line of travel of the lugs R' and abut by its end g2 againstone of them, as shown in dotted lines in Fig. G, being held there by itsspring P', so that as the gear is turned it will by such connectioncarry around with it the plate J and its pawl, and as the pawl bearsagainst the edge of the cam H' its end f2 will be gradually movedoutward, and at a certain point on the cam end it will have moved outward sufficient for its arm g2 to be free of the lug R' of the gear withwhich it is engaged, as shown in detail in Fig. 12, leaving the platefree to be swung' back to its starting position by the action of t-hecoiled spring L', which in such turning movement of the plate has beenwound up, and in such return movement the pawl will travel back alongthe edge of the cam to its first position by its spring forcing outwardits end g2 into position to abut against the next lug R' of the gear,and thus engage its plate J' again with the gear D' to be turned withit, as before, to be released again when moved so far by the cam andreturned to its first position again and be engaged therewith, asbefore, and so on.

Pivoted at n2 between two uprights r2 on the upper side of the plate Jis a vertical angular arm S having pivoted at t2 in the upper end of itsupwardly-projecting arm a2 a roller T'. Under this angular arm, near itspivot, is a spring U secured by its inner end to the plate J at lU2,which presses upward against a plate A11:2 secured by screws to theunder side of the angular arm, its outer surface being in a linesubstantially concentric to its pivot.

Y is a flat spring secured to the top of the plate J by one end at a2and extending round in a curved line and bearing by its free end b2 onthe upper side of the horizontal arm cl2 of the angular arm S" to holdit down, the arm being limited in its downward movement by resting on ascrew TV screwing into the plate J, the screwing in or out of whichadjusts the height of its bearing-surface. This spring V has a notch orshoulder e2 on its upper side, against which the end or shoulder f3 ofthe angular lever is arranged to bear at times and which by itsengagement therewith, as shown in Figli, serves to hold the roller endof the angular arm back a certain distance, and preventing its movingforward until it is released by pressing down upon the thumb end g2 ofthe spring V', when the arm S by the action of the spring U will beswung forward and its shoulder just past the shoulder of the spring Y',as shown in Fig. 4C. This angular arm is so situated in regard to thespool placed in the machine that its wheel or roller T will bear uponthe edge or periphery of the spool-head, and when it is in its normalposition-that is, its shoulder e2 engaged with the shoulder f3 ofthespring D', as shown in Fig. ll-its wheel T' will be moved away a shortdistance from the spool-head; but when the spring U is pressed down torelease the arm its spring V acts to move the roller end of the armforward, which brings the roller to bear rnlly against the edge orperiphery of the spool-head, as shown in Fig. l in dotted lines, andwhen in such position the central vertical line of the wheel will bearupon the spool edge at the central line of the spool-head, as shown indetail in Fig. 8, and the arm is so arranged that the central axial lineof the wheel will be in the samehorizontal plane of the centrallongitudinal axial line of the shafts carrying spool-V holding plates ordisks, as shown in Figs. l, and f3 more particularly.

The stop-screw W is adjusted so that the arm S will not rest thereon atthe time the wheel is bearing on the spool edge, in order that the fullstrength of the spring V shall act thereon, but it stops the arm frommoving too far when the spool is not in the machine. As there are twoheads of the spool to be covered, and as it is desirous that in theoperation of the machine both should be covered at once, the transverseplate, angular arms, its gear d and parts connected therewith areduplicated, there being one set for each head, as shown in Figs. l and2, each set being constructed alike and which are lettered alike,

but eachhaving a separate worm E', which are arranged on the oppositeside of their respective worm-gears, as shown in plan view in Fig. 2,for the following reasons: In Figs. l and 2 the angular arm S at theright in operation should and does swing to the left and the angular armat the left should and does swing to the right, as shown, respectively,by the arrows in Fig. 2. Therefore, although the worms turn in the samedirection, being on,

opposite sides of the gears, as shown, they operate to turn the gears inthe required and opposite directions.

The shaft or arbor F of each worm extends forward and turns in separatebearing-plates A2, which are firmly secured to an arbor or pin B2 whichis secured to a bracket C2 of the lathe-bed by screw-nut 71,2 andshoulder m2, and each worin-shaft has a small gear C2 which engages witha larger gear D2 arranged between them, adapted to turn on said arborB2.

The worm-shaft F at the left extends beyond the bearing to have a handleE2 secured thereto by which it can be turned, which is to the right,Figs. l and 2, and by the gear D2 motion is communicated to the otherwormshaft. The bracket is secured by bolts n2 to the under side of thelathe-bed, and the arbor B2 is secured in a vertical open slot F2 in thebracket, so it can be moved up and down to adjust its height, and whenadjusted it is tightened by its screw-nut h3, which firmly secures thebolt or arbor in its place on the bracket. Turning this worm by itshandle E2 to the right by its gear C2 and gear D2, connecting with theother gear C3 of the other worm, the other worm-gear is turned in thesame direction; but as they are on opposite sides of the worm-gears theworm-gears are turned to the rightand left correspondingly.

To upright arms 2 of each plate A is pivoted at 'a2 a lever G2, which byone arm r2 extends under the spring V on its respective plate, theirother ends 102 extending back for operation thereof, and which can bedone by connecting both with a treadle for operation of both at the sametime or independently if desired. This lever G2 is held up by a springH2 secured to the arm t2, by which its end is kept from interfering withthe movements of the angular arms S, except as above described. Theselevers are for the purpose of raising the springs V off the angular armswhen desirous of having the angular arms released from their pressureupon the spoolheads to allow the springs U to act to engage theirshoulders e'9 with the shoulders f2 on the under side of the angulararms, and these levers are operated for such purpose when the angulararms have been swung by their gears the requisite distance and it isdesired to return them to their normal position for operation again.

The metal A3 to be placed over each head of the spool is rst cut out ofa flat sheet of metal of the proper thickness in circular form, and insuch die the outer edge a4 is turned IOO IIO

over at right angles thereto, as shown in crosssection in Fig. S. It isthen placed in another die and punch, the central portion cut out, andthe part next thereto pressed and molded into the outline shown incross-section at bAl in Fig. 8. Each spool-head is then turnedpreviously in a lathe to have its head edge round in cross-section witha flat groove in its outer side at d* to receive the portion ZJ'L of themetal plate and preferably a small narrow groove in the inside at el,the width of the plate being sufcient to extend over the edge of thespool-head as desired and be disposed in the grooves.

To operate the machine, two of the metal coverings being prepared asdescribed are placed one over each spool-head, as shown in Fig. 8, andthe spool placed in the machine as before described, and the pulley setin motion, which revolves its shaft and spool with it. The two rollersdo not yet bear upon the spool-heads, but press down the two springs U',which relieves them from their interlock with the angular arms S',allowing their springs V to act upon them to press their rollers againsttheir respective spoolheads, each one bearing against the metal at thecentral line of the curve, as shown in detail in Fig. S. The handle E2of the wormscrew at the left is now turned to the right, which turns thegears carrying their respective plates and rollers to the left and tothe right, the edges of the rollers in their horizontal travel moving inthe path of a circle and being held firmly to their bearing on the metalby their springs. As the rolls are carried round the edge of each headthe metal covering to each head is rolled and forced around the edge ofthe head to its inner side, the rolls taking the several positions andin -continuation thereof shown in detail in Figs.

8, 9, and l0, and when at the edge of the metal, as shown in Fig. 10,the pressure of the springs V' forces the rolls to turn the edge of themetal into a groove in the outside of each head or compresses the metalinto the head at such place if no groove is provided. Then thus fullycovered, the levers G2 are pulled down at their outer ends, which thenby their inner ends bear up against the under side of the springs andraise the springs from the angular arms, (which by their rotatingmovement have moved into such position over the inner ends of thelevers,) which swings them against their springs and the rolls fromtheir bearings on the spool-heads, so that the arms engage by theirshoulders f3 with the shoulders c3 of the springs U', which holds themin such position and leaving them free so the coiled springs L' can thenact to swing back the plates and their angular arms into their normalpositions ready for operation upon other spools, as before.

rllhe cam-plates H' are stationary, and as the gears D with their platesand roller-arms are turned on their axes their respective pawls N arecairied round with them, and in suoli movement their inner ends movealong the cam edge from the position shown by dotted lines in Fig. 6 tothe position shown by dotted lines in Fig. l2 for the right-hand angulararm, and being gradually forced outward their ends g2 arecorrespondingly moved inward and away from their engagement with thelugs R of the worm-gear, and by the time the rolls or wheels havecompleted their movements and work on each spool-head the pawls will bedisengaged from the lugs R', leaving their respective circular platesfree to be acted upon by their coiled springs L' L' immediately thepressure of the springs is relieved from the angular arms,and as theplates move back their pawls also move back along the portions of thecam over which they have traveled and by the action of their springs P'their arms f2 are moved inward and their ends g2 outward to strike an dbear against the next lugs R', stopping their plates and angular arms,&c., in positions shown in Fig. 2 and ready for action, as before, onthe heads of another spool.

As the gears and their plates travel in opposite directions, thecam-plates are reversed accordingly, the cam at the right being shown inplan in Fig. G and the cam at the left being opposite thereto, but notshown.

XVhen desirous of covering the heads of spools which are longer orshorter than the one shown, the blocks or plates XV, carrying theangular arms, are moved along the lathebed either to or from each other,according as the spool is longer or shorter, by unscrewing the bolts f4,which allows the plates to be moved along the lathe-bed the properdistance apart, which are then secured in place by tightening up thebolts, and if the heads are of smaller or larger diameter turning thescrew B' to the right or left will correspondingly move the plates A' ontheir respective blocks and adjust them to the desired positions, and incase of these readjustments the arbor B2 to the gear D2 is loosened andits height adjusted in the slot E2 in the bracket C2 to place the gearso it will properly engage with the worm-gears C3 to suit their changedpositions to the right or left, and when the gear is brought to itsposition the arm is firmly secured in the bracket. Obviously forextremely large spools a machine correspondin gly enlarged would benecessary, the present machine practically being limited to certainsizes of spools.

Having thus described my invention, what I claim isl.
